I do remember there was some outcry. Just about
the same time transponders were mandated.


Ross,

Where were transponders mandated in the 70's? I remember that the
expanded number of TCAs (Class B) and Mode/C requirements showed up in
the late 80's / early 90s as a result of the Cerritos mid-air crash in
'86. Before that, most planes that I flew weren't equipped with
transponders.

Just Curious.
